Well! Every time someone and in fact, I used to do CP (Competetive Programming), many times, I feel like there should be a toolkit or even a folder of all the necessary and general codes....

Well, don't worry!

I have made a GitHub Repository, with all the required and general necessary codes. We are still upgrading it whenever we find time!

I hope it may help you. :)

Here is the Repo link :

Also if someone finds something missing there, which definitely be there😅. You are welcome to contribute to this!

Thank you!
